The VOP on RK3399 has a different approach from previous versions for
setting a gamma lookup table, using an update_gamma_lut register. As
this differs from RK3288, give RK3399 its own set of "common" register
definitions.

The RK3399 has a 1024-entry gamma LUT with 10 bits per component on its
"big" VOP and a 256-entry, 8 bit per component LUT on the "little" VOP.
Compared to the RK3288, it no longer requires disabling gamma while
updating the LUT. On the RK3399, the LUT can be updated at any time as
the hardware has two LUT buffers, one can be written while the other is
in use. A swap of the buffers is triggered by writing 1 to the
update_gamma_lut register.

Changes from v1: Moved the vop_crtc_gamma_set call to the end of
vop_crtc_atomic_enable after the clocks and CRTC are enabled.
